Abstract: Abstract of the Disclosure A push arm assembly for eccentrically operating a ratchet gear by means of a driving pawl to rotate an unloader arm in the bottom of a silo or the like.  Directional change of the driving pawl is accomplished by withdrawing the driving pawl into its housing and rotating it 180° and then releasing it to place the pawl in engagement with the ratchet to drive the latter in the predetermined forward or reverse rotation. The driving pawl also can then be rotated 90° into a position out of engagement with the ratchet when rotation of the unloader arm is not desired.  A holding pawl is also employed in con-junction with the driving pawl to restrain the ratchet during the period of oscillation when the driving pawl disengages the ratchet and recedes to engage the next tooth on the ratchet. Directional change of the holding pawl and disengagement from the ratchet is accomplished in the same manner as the driving pawl.

Abstract: ABSTRACT OF THE DISCLOSURE      A pair of substantially flat rectangular fusible links is constructed from progressive dies by partially cutting them from sheet metal stock as blanks, flanging edges on the parts and including the forming of triangular camming surfaces on such flanges, and then shearing the parts from the stock. Thereafter, the links are fluxed and soldered together and are held in internested complementary relation. It is characteristic of the links that there are no voids or discontinuities in the joined surfaces and into which flux will not flow; the interfacing tri-angular cam surfaces insure a clean breaking apart of the links once the eutectic temperature of the links biases them laterally apart under the camming action to insure a complete break-away of the con-fronting soldered surfaces.

Abstract: ABSTRACT OF THE DISCLOSURE   A device for sensing or measuring loads, especially transient loads, such as a load imposed by a wheel of a vehicle driving over the device. The device comprising two electrically conductive plates and an intermediate dielectric and elastomeric or elastic material.  A series of steel wires is embedded in a central plane of the dielectric material.  Said threads are connected together electrically at one end.  The wires form one capacitor electrode while another electrode is formed by the plates.  The variation in the capacitance is linearly proportional to the magnitude of the applied load. The two plates are pressed towards each other in order to create a mechanical preload in the intermediate material, in order to give said linear propor-tionality.

Granted: 1981-01-27
Abstract: ABSTRACT OF THE DISCLOSURE:         Thin invention relates to a process for producing and maintaining a fluidized bed in a heterogeneous system and to an apparatus for carrying out the same.   This process essentially comprises feeding the heterogeneous system in a column between at least two bases arranged over one another, opposed to one another and inclined in relation to the horizontal, said column forming a turbulent compartment in which the heterogeneous system is stirred in a turbulent movement because of the gravity and in which the heavier phase concentrates above the lower base, especially in its lower area, and from there flows into the space below the lower base while the lighter phase concentrates below the upper base, especially in its upper area, and from there flows into the space above the upper base or is conducted out of the column, the disperse phase thus being conducted through the column either in the direction from top to bottom when having a density greater than that of the continuous phase, or in the direction from bottom to top when having a density smaller than that of the continuous phase.

Abstract: ABSTRACT OF THE DISCLOSURE:           A removable, knock-down partition assembly for use in a bottle-carrying container. The partition assembly has a main partition and secondary partitions. The secondary partitions are rotatably connected to the main partition for movement between a first, knock-down position where they lie substantially flat against the main partition and a second, set-up position where they are substantially perpendicular to the main partition.          Means are provided for locking the partitions in the second position.  The means for connecting the partitions together comprise a slot in the main partition for each secondary partition, a socket at the bottom of each slot, and a pivot pin on each secondary partition insertable into the socket when the secondary partition is inserted into a slot. The locking means comprise a locking tab on one edge of each slot, and means on the tab for retaining the secondary partition substantially at right angles to the main partition. The edges of each slot are slightly laterally offset to opposite sides of the body of the main partition, the retaining means on the tab retaining the secondary partition against the offset edges when it is in the second position.

Abstract: ABSTRACT OF THE DISCLOSURE       A method of making a dynamically balanced cup-shaped blank for use in the production of a V-grooved pulley, from a flat sheet metal disc by a roller spinning tool.  The disc is provided with a central hole for mounting the disc on rotating die means between headstock and tailstock die form assemblies of a spinning machine.  The spinning tool presses the disc against an end of a headstock die form and moves generally radially out-wardly pressing a portion of the disc against the end of the die form to provide a bottom wall of the desired cup-shaped blank. The spinning tool then moves in a series of passes along the headstock die form thereby rolling, forming and ironing rotating outer metal portions of the disc against the die, and forming the disc with an annular reversely angled conical flange and an axially extending cylindrical side wall which terminates in an open end.  The die form and spinning tool also form a reentrant corner in the disc blank which connects the conical flange with the cylindrical wall and which is defined by an acute angle with the cylindrical side wall.  The conical flange ultimately forms a portion of one of the flanges of a V-groove in a finished pulley subsequently spun from the cup-shaped stage blank.  The open end of the cylindrical side wall ten is trimmed to a pre-determined length to provide the desired wall length in which one or more V-grooves will be spun, to form a finished dynami-cally balanced, spun V-grooved pulley.

Abstract: ABSTRACT OF THE DISCLOSURE Xerographic plates, particularly xeroradiographic plates, suitable for soft or hard x-ray exposure require margins or edges suitable for handling and mounting.  In order to fabricate such plates, it is convenient to apply a peripheral mask over the substrate during application of at least the photo-conductive layer.  Use of masks, however, tend to promote peripheral plate irregularities, usually because of scratches or other uneveness at or under the margin of the applied mask. Such imperfections spawn corresponding electrical field irregularities which can now be minimized or avoided altogether by grounding the margins with metal overcoats.

Abstract: ABSTRACT OF THE DISCLOSURE            A bracket has a base or back that can be attached to a support, and spaced-apart, substantially vertical pro-jections or flanges extend out from the hack.  The flanges are loading-bearing and spaced apart to leave two side-by-side U-shaped recesses of unequal width.  The recess of greater width is dimensioned to receive the two flanges that define the recess of lesser width when in identical and second bracket is posi-tioned opposite the first and the flanges of the two brackets interfitted.  Thus, a bracket pair is formed with their wide and narrow recesses being interfitted.  At the bottom of the narrow recess, a captured nut on an apertured tab is positioned to receive a threaded screw of bolt from above.  A strip with holes bridges the upper edges of the flanges of both brackets of the pair and screws can be passed through the holes between the flanges to engage the nuts at the lower ends of the narrow recesses.
